Detailed ways

Blockchain technology is essentially a distributed storage technology. Each node in the blockchain network is based on a consensus mechanism. It can perform consensus verification on transactions between nodes, and then store the transactions that have passed the consensus verification into its own shared ledger ( (That is, the blockchain), so as to ensure that the transaction records in the shared ledger cannot be tampered and traceable. Because of this characteristic of blockchain technology, it has great application prospects in the field of crowdfunding business.

However, the existing blockchain-based crowdfunding method is relatively simple, and users can only passively fund crowdfunding projects initiated by others.

In addition, due to differences in beliefs, experience, and financial capabilities between people, some people may be interested in a crowdfunding project, and some may be interested in a crowdfunding project. not interested. This results in that it is not easy for a crowdfunding project to find people who are willing to fund it. The fundraising process may be protracted and not conducive to the rapid implementation of the project. It can be seen that the existing blockchain-based crowdfunding method still has the problem of low efficiency. However, there is currently no blockchain-based crowdfunding method that can solve the above problems.

For this reason, in one or more embodiments of the present specification, a number of project categories are preset, allowing users to choose from which project categories they are more concerned about, and pre-funding in the form of delivery of virtual resources, that is, users do not have to wait for specific crowdfunding. The project can only be funded when it is launched, but is funded for a certain project category. Later, when a crowdfunding project corresponding to this project category is launched, the user's previously funded property can be directly drawn.

In other words, the user does not need to passively understand each specific crowdfunding project initiated by others and decide whether to fund it. Instead, he actively delivers virtual resources to some of the project categories he cares about, and the user delivers virtual resources to a certain project category. Resources are equivalent to funding for this project category. Virtual resources can be converted into property. The more virtual resources corresponding to a project category, the more funding available to the crowdfunding project corresponding to that project category. When a crowdfunding project corresponding to the project category is launched, it can be directly withdrawn from the virtual resources corresponding to the project category, converted into property, and the crowdfunding project can be promoted as soon as possible without having to spend time on fundraising.

In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present specification, the technical solutions in the embodiments of the present specification will be described in detail below with reference to the drawings in the embodiments of the present specification. Obviously, the described implementation The examples are only a part of the embodiments of this specification, but not all the examples. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art should fall within the protection scope.

The technical solutions provided by the embodiments of the present specification will be described in detail below with reference to the drawings.

FIG. 1 is a schematic flowchart of a blockchain-based virtual resource delivery method provided by an embodiment of this specification, including the following steps:

S100: The delivery node in the blockchain network obtains the category identifier and resource amount specified by the delivery user.

S102: The delivery node constructs a target transaction based on the category identifier and the resource amount.

In the embodiment of the present specification, several item categories can be preset, and a category identifier is assigned to each item category. Among them, the project category can be set according to the actual business needs.

Next, a business scenario is proposed in this article, and the technical solution of the present invention will be specifically described in combination with the business scenario in many places in the following. It is worth emphasizing that this business scenario does not constitute a limitation on the technical solution of the present invention. In fact, the business scenario to which the technical solution of the present invention is applicable is various, and it may be any specific business scenario involving crowdfunding services, such as Public welfare crowdfunding.

A business scenario proposed in this article is that in real life, art lovers often initiate a variety of crowdfunding projects in memory of a deceased art worker. For example, a crowdfunding project to repair Borges's former residence, a crowdfunding project to hire a university professor to hold an Eliot poetry lecture, and so on.

In this business scenario (for the convenience of description, this business scenario will be referred to as a literary scene hereinafter), a project category can be a late literary and art worker, and a category identifier can be a late literary and artistic work Identity of the person.

In the embodiment of the present specification, a node in a blockchain network may be a user device, and specifically may be a user's mobile phone, computer, or other device with data processing and storage functions. It should be noted that, in the following, for the convenience of description, the expression "the node corresponding to the user performs XX operation" is no longer used, but the expression "the user performs XX operation" is directly used. It should be understood that when some operations When it is only suitable for device execution, "user executes XX" actually means "node corresponding to user performs XX operation".

It should also be noted that users need to connect their own user equipment to the blockchain network so that their own user equipment is called a node in the blockchain network in order to be able to deliver virtual resources.

In the blockchain network, any user can deliver virtual resources (equivalent to funding) for a certain project category through their corresponding nodes. The delivery user actually refers to a user who currently wants to deliver virtual resources, and the delivery node actually refers to a node corresponding to the delivery user.

When a user wants to perform virtual resource delivery for a certain project category, he can specify the category identifier of the project category, and also need to specify a resource amount. Wherein, the amount of the resource is a measurement value of the virtual resource, and the virtual resource is essentially valuable information that can be circulated on the network, and specifically may be points, tokens, virtual items, and the like. For example, the virtual resource is points, and the user specifies a resource amount of 20, which means that the user wants to deliver 20 points.

In the embodiment of the present specification, virtual resources can be exchanged for property, and the property can be legal tender or other valuable property. The conversion rules between virtual resources and property can be specified as needed. For example, the virtual resource is points and the property is RMB. The conversion rule of virtual resources and property can be 1 point for 1 yuan.

After the delivery node obtains the category identifier and the resource amount specified by the delivery user, it can construct a target transaction based on the category identifier and the resource amount. As we all know, in the field of blockchain technology, transactions can generally refer to business data with business intent. In the embodiment of the present specification, the target transaction is actually business data including the category identifier and the resource amount.

In the art scene, the delivery user may be an art lover who wants to deliver virtual resources to a deceased art worker, and the delivery node may be a node corresponding to the art lover. For example, Zhang San is a loyal reader of Borges' works. If Zhang San wants to show his support and commemoration of Borges, he can initiate a virtual resource delivery operation for the preset Borges identity . Specifically, Zhang San can enter the identity of Borges (such as Borges-Argentina-18990824) and the amount of resources (such as 200) of the virtual resources he wants to deliver into his mobile phone. Borges-Argentina-18990824 and 200, build target transactions.

S104: The delivery node broadcasts the target transaction to the blockchain network.

S106: Multiple nodes in the blockchain network obtain the target transaction and perform consensus verification on the target transaction.

S108: If the consensus verification is passed, the plurality of nodes establish a first correspondence relationship between the category identifier and the virtual resource of the resource amount, and store the first correspondence relationship in its own shared ledger.

In the embodiment of the present specification, after the delivery node has constructed the target transaction, the target transaction may be broadcasted, so that multiple nodes in the blockchain network that need to perform consensus verification on the target transaction can obtain the target transaction. Target transaction. The plurality of nodes may be all nodes in the blockchain network, or may be some nodes in the blockchain network.

The consensus verification of the target transaction by the multiple nodes may include whether the signature of the target transaction by the delivery node is legal, and / or whether the target transaction has been tampered with during the broadcast process. The specific verification method should be known to those skilled in the art, and will not be repeated here.

If the target transaction passes the consensus verification of the plurality of nodes, the plurality of nodes establish a first correspondence relationship between the category identifier and the virtual resource of the resource amount, and assign the first correspondence The relationship is deposited into its own shared ledger (that is, the blockchain).

In this way, for each project category, the virtual resources corresponding to the project category can be converted into property for funding the crowdfunding project corresponding to the project category.

In addition, it should be noted that in practical applications, for each project category, any node in the blockchain network can be used as a delivery node, and virtual resource delivery is performed for the project category. One delivery will generate one project category. A first correspondence between a category identifier and a virtual resource of a certain resource amount.

That is, for each project category, a first correspondence relationship generated by one delivery is actually a delivery record corresponding to the project category. By tracing all delivery records corresponding to this project category on the shared ledger, the cumulative amount of delivery of virtual resources corresponding to this project category can be determined.

In a literary scene, for example, the virtual resource may be an electronic symbol of a scarecrow image. One "scarecrow" delivered can represent a memorial to the deceased literary and art worker, and one "scarecrow" can be exchanged for 100 yuan. A literary and art enthusiast makes a scarecrow delivery for a deceased literary and art worker, which is equivalent to other literary and art enthusiasts who request access to the blockchain network. Immutable.

For the identity of each deceased literary and art worker, the cumulative delivery amount corresponding to that identity can be regarded as the "popularity" accumulated by the deceased literary and art worker.

Table 1 shows the delivery records stored on the shared ledger in the literary scene.

Table 1

As shown in Table 1, one row corresponds to one delivery record (that is, a first correspondence relationship generated by one delivery). Each delivery record is arranged from top to bottom in chronological order. Each delivery record may come from a different delivery node. By tracing back in the shared ledger, the "popularity" of each deceased literary and art worker can be determined. For example, it can be determined that Borges' "popularity" is 5 + 6 = 11.

In addition, the foregoing embodiment only records the category identifier and the corresponding resource amount of the project category targeted for one delivery into the shared ledger for recording, but does not store the identity information of the delivery node in the shared ledger for recording.

In order to reflect the identity information of the delivery node in the delivery record, in step S102, a target transaction may be constructed based on the category identifier, the resource amount, and the node identifier of the delivery node. Accordingly, in step S108, after the target transaction passes the consensus verification of the plurality of nodes, the plurality of nodes may establish a first correspondence among the category identifier, the resource amount, and the node identifier. Relationship, and the first corresponding relationship is stored in its own shared ledger.

In this way, in the literary scene, the delivery records stored on the shared ledger can be shown in Table 2.

Table 2

In the embodiment of the present specification, when the plurality of nodes participating in the consensus verification of the target transaction are part of nodes in a blockchain network, the plurality of nodes may specifically be nodes that meet specified conditions. The specified condition is a node having a first correspondence between a node identifier and the category identifier, or a node specified in advance. That is, the node that can perform consensus verification on the target transaction is either a node that has delivered virtual resources for the project category identified by the category, or a node that is specified in advance.

Here it is necessary to explain the pre-designated nodes. If only nodes that have delivered virtual resources for the project category identified by the category are required to be eligible to participate in the consensus verification of transactions constructed based on the category identification, then it will result in that for each of the blockchain networks As far as the node is concerned, the node only stores the delivery records corresponding to the project categories funded by the node. For this reason, in order to make at least one node in the blockchain network that stores delivery records corresponding to all project categories (that is, full delivery records), at least one node can be designated in advance, and the pre-designated node can participate in broadcasting to any node The consensus verification of the transaction can also save the delivery records generated by each delivery (regardless of which project category is targeted) into its own shared ledger.

For example, in the literary and artistic scene, it may be provided that, for each literary and artistic worker, only the nodes that have delivered virtual resources to the literary and artistic worker can participate in the consensus verification of transactions related to the literary and artistic worker. . Assume that a user has performed virtual resource delivery for multiple writers and artists, then this user is entitled to participate in the verification of consensus on all transactions related to one of the multiple writers and artists. In addition, it can also be stipulated that a node with higher authority can be set up, this node can participate in the consensus verification for all transactions, and store the full amount of records.

In this specification, the delivery user can own a certain amount of virtual resources, and then, based on the total amount of virtual resources owned by himself, the virtual node is delivered by the delivery node (case 1). The delivery user may not own the virtual resource, but instead commits a resource amount when the virtual resource is delivered, and when the subsequent need to cash out the virtual resource of the said resource amount into the property, the delivery user pays the equivalent property (Case 2).

For case one, a virtual resource account for storing a virtual resource may be specifically created for each node in the blockchain network in advance, and the virtual resource account is managed by a designated device. Wherein, the designated device may be a device that is responsible for redeeming virtual resources as property.

In this way, after the target transaction passes the consensus verification of the multiple nodes, the delivery node may send the resource amount to the designated device, so that the designated device is deducted from the virtual resource account of the delivery node The resource amount is a virtual resource.

In addition, for case one, the embodiment of the present specification also provides a method for recharging virtual resources. Specifically, the delivery node may obtain a recharge amount specified by the delivery user, and then send the recharge amount to the designated device, so that the designated device stores virtual resources of the recharge amount into a corresponding one of the delivery node. A virtual resource account, and a property equivalent to the virtual resource of the recharge amount is deducted from the property account of the delivery user. The property account of the delivery user may be a user's bank account, electronic payment account, or the like.

For example, assuming that the conversion rule between virtual resources (points) and property (RMB) is 1 point for 100 RMB, users can spend 500 RMB to recharge 5 points in the virtual resource account corresponding to their user equipment.

It should also be noted that, for case one, after the delivery node broadcasts the target transaction to the blockchain network, the matter that the multiple nodes perform consensus verification on the target transaction may further include: Whether the balance of the virtual resource account is sufficient (that is, verifying whether the amount of the virtual resource in the virtual resource account is not less than the amount of the resource).

Through the blockchain-based virtual resource delivery method shown in Figure 1, users can proactively deliver virtual resources for a certain project category to various crowdfunding projects that may occur in the future corresponding to a certain project category. Donate. When a user initiates a crowdfunding project of a certain project category, he can directly withdraw from the virtual resources corresponding to the project category and convert it into property, so that the implementation of the crowdfunding project can be advanced as soon as possible.

In addition, in the embodiment of the present specification, before step S102, the delivery node may obtain additional conditions specified by the delivery user. In step S102, the delivery node may construct a target transaction based on the category identification, the resource amount, the node identification of the delivery node, and the additional conditions. In step S108, the plurality of nodes may establish a first correspondence relationship between the category identifier, the virtual resource of the resource amount, the node identifier, and the additional condition.

Among them, the delivery user can specify any additional conditions according to his needs when delivering virtual resources. When someone initiates a public welfare project and requests to withdraw virtual resources with additional conditions, the additional conditions must be met in order to successfully withdraw this part of virtual resources. . The additional condition may specifically be a limitation on the use of the virtual resource delivered by the delivery user when the virtual user delivers the virtual resource.

For example, referring to Table 2, for the delivery record of the first row, suppose that when Zhang San originally made the scarecrow delivery, he specified the additional condition "only for the repair of the former residence". For the delivery record of the third row, it is assumed that When Wang Wu initially delivered the scarecrow, he specified the additional condition "only for literary lectures". Then, for a more complete form of Table 2, see Table 3.

As for how the aforementioned restrictions work in crowdfunding, we will explain later.

Based on the blockchain-based virtual resource delivery method described above, an embodiment of this specification also provides a blockchain-based crowdfunding method. Figure 2 is a schematic diagram of the corresponding process, including the following steps:

S200: A crowdfunding node in a blockchain network obtains project information of a crowdfunding project initiated by a crowdfunding user, and determines a category identifier of a project category corresponding to the crowdfunding project.

In the blockchain network, any node can initiate a crowdfunding project for crowdfunding. For convenience of description, the execution subject of the crowdfunding method shown in 2 is referred to as "crowdfunding node", and the user corresponding to the crowdfunding node is referred to as "crowdfunding user".

In the embodiment of the present specification, a crowdfunding user may initiate a crowdfunding project through a crowdfunding node, the crowdfunding node obtains project information of the crowdfunding project, and determines a category identifier of a project category corresponding to the crowdfunding project. A crowdfunding user may directly provide the category identifier to a crowdfunding node, or the crowdfunding node may determine the category identifier according to a keyword included in the project information.

S202: The crowdfunding node determines a consumption amount corresponding to the budget information according to the budget information included in the project information.

The budget information includes an amount of property required to implement the crowdfunding project. The crowdfunding node may determine the consumption amount according to the budget information and preset conversion rules for virtual resources and property. The consumption amount is the amount of virtual resources to be consumed in order to obtain the property amount in the budget information.

S204: The crowdfunding node sends the category identification and the consumption amount to multiple nodes in the blockchain network.

S206: The plurality of nodes establish a second correspondence relationship between the category identifier and the consumed virtual resource, and store the second correspondence relationship in its own shared ledger.

In the embodiment of the present specification, when the crowdfunding node obtains the category identifier and the corresponding consumption amount of the project category corresponding to the crowdfunding project, the category identifier and the consumption amount may be sent to the multi-blockchain network. Nodes. The meanings of the multiple nodes are the same as the multiple nodes in the method shown in FIG. 1. For related explanations, refer to the foregoing, and details are not described herein again.

The plurality of nodes will establish a second correspondence relationship between the category identifier and the consumed virtual resource, and store the second correspondence relationship in its own shared ledger. Among them, for each project category, a second correspondence relationship generated by one crowdfunding is actually a consumption record of virtual resources corresponding to the project category.

It can be seen that for each project category, the first correspondence relationship containing the category identifier of the project category actually represents the increase of the virtual resource corresponding to the project category, and the second correspondence relationship containing the category identifier of the project category actually represents The reduction of virtual resources corresponding to the project category.

Further, the manner in which the plurality of nodes store the second correspondence relationship in their own shared ledger may be to modify the virtual resource of the consumed amount included in the second correspondence relationship to a negative value and store it. For example, Table 4 shows the delivery records and consumption records stored on the shared ledger.

By tracing all funding records and all expenditure records corresponding to a project category on the shared ledger, the balance of the virtual resources corresponding to the project category can be determined.

Table 4

As shown in Table 4, for each record, if the points in the record are positive, the record is a delivery record, and if the points in the record are negative, the record is a consumption record.

In the embodiment of the present specification, in order to make each consumption record on the blockchain include the identity information of the corresponding crowdfunding node, before step S206, the crowdfunding node sends its own node identification to the multiple Node, in step S206, the plurality of nodes establish a second correspondence relationship among the category identifier, the consumption amount, and the node identifier. As shown in Table 5, each consumption record contains the initiator information (that is, the node identification of the crowdfunding node) of the public welfare project that consumes the scarecrow, and each delivery record contains the information of the delivery party (that is, the node identification of the delivery node).

S208: The crowdfunding node converts the consumed virtual resources into properties for funding the crowdfunding project.

Through the blockchain-based crowdfunding method shown in Figure 2, crowdfunding users can quickly raise virtual resources required to implement crowdfunding projects through crowdfunding nodes. Crowdfunding users can use the collected virtual resources to request conversion to the corresponding property to the specified device described above.

Taking the art scene as an example, suppose a certain art enthusiast Zhang San wants to organize an event to commemorate the XX anniversary of the death of Borges. Zhang San can launch a crowdfunding project. The project information of the crowdfunding project includes "Commemorating Bor The budget for the XX anniversary of Hess's death is 30,000 yuan. " Zhang San can use a mobile phone (crowdfunding node) to determine the number of scarecrows required to implement this event is 300 (one scarecrow can be exchanged for 100 yuan), and then the identity identification (ie category identification, such as Borges) of Borges -Argentina-18990824) and 300 (amount of consumption) are sent to multiple nodes in the blockchain network, and the multiple nodes establish a second correspondence between Borges-Argentina-18990824 and 300, and the following Consumption records are stored in its own shared ledger.

Borges-Argentina-18990824

-300

In addition, in the crowdfunding method shown in FIG. 2, before step S208, the crowdfunding node may send the project information to multiple nodes in the blockchain network, so that the multiple nodes are confirming After the item information is described, a second correspondence relationship between the category identifier and the consumed virtual resource is established, and the second correspondence relationship is stored in its own shared ledger. In this way, the crowdfunding node cannot freely withdraw from the virtual resources corresponding to the category identifier, but instead submits the project information of the crowdfunding project it initiated to the multiple nodes for review, the multiple nodes After the confirmation (that is, the verification is passed), the crowdfunding node can successfully withdraw the required virtual resources from the virtual resources corresponding to the category identifier.

In the literary scene, it may be provided that, for each artist, only users who have delivered virtual resources to the artist are eligible to participate in the review of crowdfunding projects related to the artist.

Further, as described earlier, the delivery node may specify additional conditions when performing virtual resource delivery. Based on this, when the multiple nodes are reviewing a crowdfunding project, if there is an additional condition on the virtual resources requested by the crowdfunding project, the multiple nodes may review according to the additional condition.

Specifically, for each of the multiple nodes, when a first additional condition exists, the node reviews the item information according to the first additional condition, and if the item information meets the first additional condition, With additional conditions, the node determines that the project information passes the audit. If the project information does not meet the first additional condition, the node determines that the project information fails the audit; the first additional condition is that the A node ID corresponding to the node and an additional condition corresponding to the category identifier; when the first additional condition does not exist, the node determines that the project information passes the audit; and if the multiple nodes target the project information If a consensus is reached through the review, the project information is confirmed.

Wherein, the consensus strategies adopted by the multiple nodes for consensus on the project information through review can be various, such as simple voting rules or complex consensus mechanisms, which are not specifically limited in this specification. .

Suppose Wang Wu has launched a crowdfunding project "Commemorating the XX Anniversary of Borges's Death with a budget of 300 yuan". It can be seen that Wang Wu needs to draw 3 scarecrows from the corresponding Scarecrows in Borges. Suppose Table 3 shows the delivery records stored on the current blockchain. It can be seen that the number of scarecrows corresponding to Borges is 5, and all of them come from Zhang San's delivery. And when Zhang San delivered the scarecrow, he specified the additional condition "only for the renovation of the former residence", so the multiple nodes will not actually reach a consensus on the crowdfunding project through review, and Wang Wu cannot get 3 scarecrows. .

Still use this example. Suppose the following table 6 shows the delivery records stored on the current blockchain. It can be seen that the number of scarecrows corresponding to Borges is 8, among which 5 scarecrows are from Zhang San's delivery and 3 scarecrows are from Li Si Delivery. Therefore, even if Zhang San specified the attachment conditions when delivering the scarecrow, the multiple nodes may not have to consider when reviewing the crowdfunding project, but allow Wang Wu to take priority to the scarecrow delivered by Li Si (no additional conditions) .

Table 6

In addition, in practical applications, for each item category, among the multiple nodes, nodes corresponding to the category identifier of the item category form a node set corresponding to the item category. When a crowdfunding user can initiate a crowdfunding project involving multiple project categories, the multiple nodes confirm the project information of the crowdfunding project, which may specifically be:

Each node set determines whether to confirm the item information, and if each node set reaches a consensus on confirming the item information, the plurality of nodes confirm the item information.

For each item category, the process of determining whether to confirm the item information by the node set corresponding to the item category may be as follows:

1. For each node in the node set, when a second additional condition exists, the node reviews the item information according to the second additional condition, and if the item information meets the second additional condition, Then the node determines that the project information passes the audit, and if the project information does not meet the second additional condition, the node determines that the project information fails the audit; the second additional condition is that the node with the node Identification, and additional conditions corresponding to the category identification of the project category;

2. When the second additional condition does not exist, the node determines that the project information passes the review;

3. If each node in the node set reaches a consensus on the project information through review, the node set confirms the project information;

4. If each node in the node set fails to reach a consensus on the item information through review, the node set refuses to confirm the item information.

For example, suppose Li Si has launched a crowdfunding project "Borges and Carver Works Comparative Evaluation Lecture, with a budget of 1,600 yuan". It can be seen that Wang Wu needs to choose from the Scarecrows corresponding to Borges and the Scarecrows corresponding to Carver. A total of 16 scarecrows were withdrawn. Assume that Table 6 shows the delivery records stored on the current blockchain. It can be seen that the number of scarecrows corresponding to Borges is 8, and the number of scarecrows corresponding to Carver is also 8. When Jorge delivered the Scarecrow, he specified the additional condition "only for the renovation of the former residence", and when Wang Wu delivered the Scarecrow to Carver, he specified the attachment condition "only for the literary lectures".

Li Si sends the project information of the crowdfunding project to Zhang San and Wang Wu. The nodes that need to review the project information are Zhang San, Li Si, and Wang Wu. Among them, Zhang San and Li Si form a Borges correspondence. The node set 1 of Wang and Wang Wu form the node set 2 corresponding to Carver. Node set 1 will internally agree on whether the project information has passed the audit, and node set 2 will also internally agree on whether the project information has passed the audit. Assuming that the consensus rule is "subject to the majority opinion", since Zhang San specified the additional condition "only for the renovation of the former residence" when delivering the scarecrow to Borges, the node set 1 failed Reach consensus on the project information through review. Even if the node set 2 internally reached a consensus on the project information through auditing, between the two sets of node set 1 and node set 2 could not finally reach a consensus on the project information through auditing. In the end, the crowdfunding project initiated by Li Si failed to be implemented.

Finally, it should be noted that after the crowdfunding project initiated by the crowdfunding node has successfully raised the property, the crowdfunding project can be implemented. During the implementation of the crowdfunding project, the use of the raised property can also be broadcasted by the crowdfunding node to the blockchain network, and multiple nodes in the blockchain network will be deposited in the blockchain for publicity.
